The 11 Best Dietitian-Backed Colostrum Supplements

Since colostrum has been shown to aid muscle recovery and boost athletic performance, Transparent Labs created a product that purports to maximize those benefits. Offering a whopping 20 g of grass-fed colostrum per serving, this powder is designed to support peak-level athletes’ muscle development and resilience. And with the high dose comes 12 g of protein, which may help you reach your daily protein goals. It’s available in unflavored or chocolate.

Colostrum supplements can be pricey, with premium brand products costing upwards of $50 for a 30-day supply. Nutricost Colostrum is much more wallet-friendly while still delivering colostrum quality comparable to higher-end brands. You get 120 capsules (a two-month supply) for under $20, which is less than half the cost of colostrum from premium brands. Plus, the capsule format may be easier for colostrum newbies to take than the powder you have to mix in a liquid.

This colostrum is third-party tested, non-GMO, and the capsules are gluten-free and made in an NSF-Certified, GMP-Compliant facility. It’s also easily accessible as it’s widely available at national pharmacies. While we love that the capsules are relatively small, the 1,000 mg dosage is on the lower side of colostrum supplements, so this supplement is not for those looking for high potency.

One of the most common complaints with colostrum powders is that they often don’t entirely dissolve in liquid. It’s never fun to shake the powder vigorously for a few minutes only to get a wet glob of colostrum at first sip (if you know, you know). Sports Research seems to have solved that problem with its bovine colostrum powder. It dissolves quickly and completely in liquid, never leaving clumps.

While most colostrum supplements are unflavored, Armra Immune Revival stands out for its appealing flavors, with four tasty options: Blood Orange, Peach Persimmon, Sungold Apricot, and Vine Watermelon. The flavored varieties are especially convenient for mixing into water for a refreshing alternative to plain powder.

Armra’s colostrum supplement is available in stick packs, making it easy to take on the go. The product is free from antibiotics, hormones, and unnecessary fillers.

The biggest downside is that flavored options cost $10 more than the unflavored supplement, but the taste, portability, and high-quality formulation may make it a worthwhile investment.

Miracle Moo colostrum powder is an excellent choice for immune health, offering 1.5 g to 3 g of grass-fed colostrum, depending on whether you have one or two scoops. This product also has ImmunoLin, a patented ingredient that contains 50 percent IgG, providing a potent dose of immunity-supporting antibodies.

While the website doesn’t mention third-party testing, an email from customer service confirmed that Miracle Moo undergoes “rigorous third-party testing” to ensure quality and safety. The brand exclusively uses surplus colostrum, ensuring that young calves are fed and well-nourished with the colostrum they need before any is collected for this product.

The powder is unflavored and free of additives, soy, wheat, nuts, and sugar. You can mix one to two scoops into 8 to 12 ounces of water, smoothies, or your favorite recipes (although we did find it can clump if not stirred well). While it may lack the flavor variety of some competitors, Miracle Moo’s high IgG content makes it a top choice for a colostrum supplement for immune health.

A lot of colostrum products include additives to increase immunoglobulin percentage or growth factors, but not WonderCow. The brand prides itself on keeping it simple: just pure, whole bovine colostrum complete with the balance of peptides, essential amino acids, and immunoglobulins you’d get straight from the cow.

We appreciate that it’s GMP-certified, third-party tested, and made by a seventh-generation dairy farm family (so they know a thing or two about bovine colostrum). They also ensure calves receive the nourishment they need before harvesting colostrum from mother cows. Our only complaint is the consistency — when we tried this colostrum, it never fully dissolved in liquid, and the taste was at times overwhelmingly milky.

If you’re seeking a cow-free colostrum supplement, Mt. Capra Goat Milk Colostrum is our top choice. Sourced from pasture-raised goats on a family-owned farm, this product is available in capsule or powder form.

According to Durston, “Bloom’s product is an excellent choice for supporting healthy hair, skin, and nails, thanks to its blend of collagen, colostrum, and probiotics.” For these reasons, it’s our top pick for people looking for a colostrum supplement to support hair, skin, and nail health.

The product is third-party tested and free from artificial additives. You can choose unflavored, Strawberries & Cream, or Orange Cream; flavored options are sweetened with stevia. This Bloom product also contains vitamin B12, which some people may not need or want in a colostrum supplement. Still, for an all-in-one collagen and colostrum supplement, Bloom delivers.

For a convenient, easy-to-take form of colostrum, Sovereign Labs capsules top our list. “Colostrum capsules offer an alternative to powder, especially for those who take colostrum on the go or while traveling,” says Durston.

According to Amy Archer, RDN, owner of Wellness RD, who recommends this product to her clients, “Sovereign Laboratories liposomal colostrum comes from the first milk, after the calf meets its needs, from pasture-raised cows. The colostrum is tested to confirm it does not contain antibiotics, hormones, and herbicides. This liposomal colostrum is flash pasteurized to maintain bioactive substances.” These bioactive substances can include immunoglobulins (such as IgG) and other essential proteins.

While the capsule form is undeniably convenient, the serving size contains less colostrum than powders (although you could easily take more). “Unlike powders, capsules require no mixing with water and are easier to store, making them a hassle-free option for daily use,” says Durston.

We like that this product specifies the amount of lactoferrin present, unlike many other options on the market, and is third-party tested for purity, potency, and safety, with the results available on the website. However, it’s expensive, and we found that the powder requires vigorous mixing or a handheld mixer (especially since hot water is not recommended), as it tends to clump. Despite this, the product’s high-quality formulation and transparency make it our top choice for a colostrum supplement for digestive health.

While the product is simple to use, one downside is its texture. Without using a blender or frother, the powder can be chunky when mixed into liquids. “I recommend adding a scoop to plain water, juice, or smoothies or mixing it into yogurt or oatmeal bowls for easy use,” says Durston.
